Insights into Myelin Oligodendrocyte Glycoprotein Associated Disease (MOGAD): Prevalence, Clinical Manifestations, and Treatment Responses in a Four-Year Retrospective Cohort Study

Introduction: This study aims to delineate the prevalence, clinical characteristics, diagnostic findings, and treatment outcomes of Myelin Oligodendrocyte Glycoprotein Associated Disease (MOGAD) in a cohort over four years, providing a basis for improved diagnostic criteria and therapeutic strategies. Materials and Methods: In a retrospective cohort study at a tertiary care center, we analyzed medical records of 90 patients presenting with CNS demyelinating symptoms, focusing on those diagnosed with MOGAD based on the International MOGAD Panel criteria. Data on clinical presentation, serum Anti-MOG antibody testing, MRI, VEP scans, CSF analysis, and treatment outcomes were evaluated. Results: Among the cohort of 90 patients, 7 patients were identified with positive Anti-MOG antibodies, indicating a prevalence of 7.8%. Clinical manifestations varied widely, including optic neuritis, myelitis, and cerebral cortical encephalitis. Diagnostic findings highlighted the absence of oligoclonal bands in CSF analysis and diverse MRI lesions. Most patients responded well to immunosuppressive treatments, though relapses occurred in two cases. The study underscores the heterogeneity of MOGAD presentations and the importance of personalized treatment approaches. Conclusion: Our findings contribute to the growing understanding of MOGAD, emphasizing its distinct clinical and diagnostic features compared to other CNS demyelinating disorders. The study advocates for the integration of MOG antibody testing in clinical practice to enhance diagnostic accuracy and patient outcomes. Future research should aim at longitudinal and multicentric studies to validate our findings and further refine MOGAD management strategies.
